ABSTRACT
Tulić, U., & Lelo, S. Basic ethological characteristics of Leptidea sinapis (Linnaeus, 1758) (Insecta: Lepidoptera: Pieridae, Dismorphiinae) adults in local population of Ilidža. The behaviour of Leptidea sinapis Linnaeus is very interesting, in particular in the context of courtship. One population of L. sinapis has been identified in Ilidža and observed during the summer of 2007. The certain aspects of adult behaviour in the population were described. All the observed behaviour patterns in our sample were evaluated against the available published information.
Key words: Leptidea, sinapis, behaviour, ethology

SUMMARY
During the summer 2007 a population of species Leptidea sinapis Linnaeus had been observed in Ilidža. The observed population is not isolated from other neighbouring population and its habitat is typical for this species. Adult males constantly fly in search of females. They are typical patrolling species and in search for females they rely on the sense of sight. When they find a female they alight opposite to her and continuously repeat the same courtship ritual. Courting males never attempt to initiate copulation unless the female has signalled that she is receptive. They lend only rarely for nutrition or rest.
Females spend most of their lives hiding in the grass. Females are monogamous and they can ultimately decide whether or not mating will occur at courtship. Monogamy avails female with ample time to search for suitable host plants for the eggs.
The observed behaviour of the adults Leptidea sinapis Linnaeus in local population of Ilidža is normal and unusual patterns were not noted. Odd behaviour by some adult males (courting another male or other species) actually fits the pattern of behaviour that is driven by strong sexual impulse and is not unusual.
